Conclusion: Both coffee powders increased sirtuin-1 expression, but our results suggest that blended coffee had hypercholesterolemic effects which could increase cardiovascular risk. Therefore, preference should be given to Arabica coffee for the best cardiometabolic benefits of coffee.
Only aerobic exercise seems to consistently increase the expression of SIRT1 and SIRT3 and the intensity ranges from moderate to the high intensities with most of the evidence based mainly on SIRT1.
Collectively, caffeine, at physiologically relevant concentrations, increases mitochondrial content by upregulating mitochondrial biogenesis PGC‐1α‐NRF-TFAM pathway.
There are several ways to stimulate the production of sirtuins, the longevity proteins. Examples are intermittent fasting or a simple reduction in daily calorie intake, which have long been linked to an increase in average life expectancy in several species.
“In low doses, caffeine may help depression,” said Dr. Clark. The reason is because caffeine “stimulates dopamine, which is a chemical in your brain that plays a role in pleasure motivation and learning.” Low levels of dopamine can make you feel tired, moody and unmotivated, among other symptoms, she said.
Caffeine acts to increase cortisol secretion by elevating production of ACTH at the pituitary (15), although the precise mechanisms remain to be characterized.
Coffee contains compounds that can contribute to the breakdown of collagen, which is important for skin elasticity. Quitting coffee might help preserve collagen and contribute to a more youthful appearance.
Sirtuin activating compounds (STACs)
The most effective of these STACs, activating SIRT1 by more than 10 fold, is resveratrol (3, 5, 4′-trihydroxystilbene; Table 1), a natural product existing in grapes and red wines.
This study demonstrates that vitamin D-bound VDR increased the expression of SIRT1 and that vitamin D-bound VDR interacts with SIRT1 to cause auto-deacetylation on Lys610 and activation of SIRT1 catalytic activity. This is an important finding that is relevant to the actions of VDR on colorectal cancer.
Sirtuins, particularly SIRT1 and SIRT3, can be activated by fasting and further exhibit their effects in insulin response, antioxidant defense, and glycolysis. Therefore, sirtuins may have anticancer effects by shifting metabolism to a less proliferative cell phenotype as well as less prone to oxidative stress attack.
It lowers your blood sugar, decreasing your risk for insulin resistance and type 2 diabetes. It turbo-charges the energy centers in your cells, your mitochondria. It nourishes the bacteria in your microbiome.
At high ATP concentrations caffeine decreases the coupling between ATP hydrolysis and Ca inflow. It either inhibits inflow without any inhibition of the rate of ATP hydrolysis, or it stimulates the ATPase activity without stimulating Ca inflow.
To support mitochondrial health, certain dietary choices need to be made. This starts by limiting the consumption of highly processed foods and promoting the consumption of legumes, fruits, nuts, seeds, and high-fiber foods.
Sirtfoods™ comprise proprietary recipes for twenty kinds of fruits and vegetables: arugula (rocket), bird's eye chili, blueberries, buckwheat, capers, cereals, coffee, dark chocolate (85% cocoa), extra-virgin olive oil, kale, lovage, matcha green tea, Medjool dates, onions, parsley, red chicory, red wine, soy, ...
Recent findings imply that phytochemicals such as resveratrol, curcumin, quercetin, fisetin, berberine, and kaempferol may regulate the activity of sirtuins.
NAD+ levels are increased in vivo in metabolic conditions such as fasting, caloric restriction and exercise. In this sense, a low energy state (eg: fasting, caloric restriction, exercise) increases sirtuin activity by increasing the NAD+/NADH ratio.
Nicotinamide, which is released from NAD+ during the deacylation reaction of sirtuins, functions as a non-competitive inhibitor. The ability of nicotinamide to inhibit deacylation by sirtuins is dependent on the type of acyl substrates.
Vitamin D3 is a prohormone produced in skin through ultraviolet irradiation of 7-dehydrocholesterol. It is biologically inert and must be metabolized to 25-hydroxyvitamin D3 in the liver and then to 1α,25-dihydroxyvitamin D3 in the kidney before function.
Vitamin D deficiency has been associated with several autoimmune diseases including multiple sclerosis (MS), rheumatoid arthritis (RA), type 1 diabetes mellitus, inflammatory bowel disease (IBD), mixed connective tissue disease, autoimmune thyroid disease, scleroderma and systemic lupus erythematosus (SLE).
Foods that activate sirtuins are central to the diet. What foods can you eat on the sirt diet? The top 20 sirtfoods include arugula, buckwheat, capers, celery, cocoa, coffee, extra-virgin olive oil, matcha, kale, red wine, strawberries, turmeric, and walnuts.
Fasting, caloric restriction, exercise, and NAD+ boosters nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) all increase NAD+, leading to activation of SIRT1 and SIRT3 and resulting in a myriad of tissue-specific effects that improve healthspan.
That's because these foods have the ability to activate sirtuins – genes which keep us young and slim by instructing the body to repair and rejuvenate our cells. Twenty foods have been identified as being top sirtuin-triggers, and Extra Virgin Olive Oil, or EVOO, comes up seventh on the list.
Slower Skin Aging
This is a protein that gives your skin its tightness and elasticity. Once it drops, your skin starts to sag, and wrinkles appear. You make it more slowly as you age. So if you get rid of caffeine, it can help keep that aging process from speeding up.
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks. Keep in mind that the actual caffeine content in beverages varies widely, especially among energy drinks.
Eliminate or reduce caffeine.
It's the quickest way to reduce cortisol production and elevate the production of DHEA, the leading anabolic youth hormone. 200 mg of caffeine (one 12 oz mug of coffee) increases blood cortisol levels by 30% in one hour! Cortisol can remain elevated for up to 18 hours in the blood.
